I C W A 4 4 4 Patented July 30, 1935 UNITED STATES PATENT OFFICE STOPPER FOR NONREFILLABLE BOTTLES Paul-Naret, Chiswick, London, England Application April 17, 1934, Serial No. 721,036 In Great Britain April 20, 1933 6 Claims,

This invention relatesto stoppers for non-refillable bottles.

There has always been difficulty in preventing; petty fraudsby dishonest persons who dilute "8-, the contents of bottles of particularv form or hearing well-known brands, or who substitute an inferior product in such bottles.

uid from being introduced,

Itis a further object of the invention to provide. a bottle, closure which is adapted to be securely fixed in the, bottle against withdrawal and which isv so formed that it is not possible to tamper with valve means which permit liquid to flow from the bottle but which prevent liquid from flowing, into the bottle.

With these and other objects in view, the invention resides in the novel constructions, combinations and arrangement of parts as described with reference to the accompanying drawing and as set forth in the claims, it being understood that various omissions, substitutions and changes may be made by those skilled in the art without departing, from the spirit of the invention.

In the drawing:

Figural is a cross section showing a stopper, constructed in accordance with the invention, in-

serted ina, bottle,

Figure 2 is a section through line 22 of Figure. 1,

Figure 3 is an elevational view of the hollow cylindrical member,

Figure 4' is a section through line 4-4 of Figure 3,

Figure, 5. is a plan view from above of the cylindrical member,

Figurefi is a section through line 6-6 of Figure 1.

Referring to the drawing, a stopper which is generally designated X is provided with a slight downward taper throughout its length, and it comprises a hollow cylindrical porcelain member A, the top face Y of which is of smooth domed form and is preferably adapted, when the stopper is'inserted in a neck Z of a bottle, to lie just below the rim 2 of and fit closely inside the bottle neck as shown in Figure 1.

The neck Z of the bottle is either blown or ground to conform to the required shape of the stopper.

The member A is formed for about the upper third of its length with peripheral angled grooves B, (which may be less rather than more acute than shown), andfor about the middle third of its length with three rows of lugs C, the lugs of adjacent rows being positioned in staggered relationship.

Below the lugs, the member A is provided round its circumference with a row of circular ports D, and the base of the member A is provided on its inner surface with a pair of diametrically opposed bayonet recesses E with which pins F, provided on a porcelain sleeve G, are adapted to engage. The wall of the member A is preferably suitably strengthened over the recessed portions E in order to avoid any possibility of fracture at the joint. Where it is found convenient, bayonet slots or partial slots and partial recesses maybe provided in thewallof the member A, instead of recesses E.

The sleeve G is provided at its upper end with an upwardly extending flange H which acts as a seating for a disc J whichhas a curved upper surface and may conveniently be formed of rub-1 her, or other suitable material which is preferably non-buoyant.

The upper surface of the disc J is adapted, when the bottle is in an upright position, to contact with a float K, which is of cork or other buoyant material and is tapered as shown, and the upper surface of the float K is adapted to contact with a cylindrical casing L of porcelain or other suitable material. The shape of the float is of considerable importance as it is necessary to allow enough freedom of movement at the bottom to permit the float to, tilt when the bottle is at any angle; this action forces the lower edge of the float against the curved upper surface of the disc J andtightens the latter against its. seat.

The three last mentioned members J, K and L respectively are pressed into contact one with another by a weight M which is preferably shaped as shown and is formed of metal or glass weighted with metal, or enamelled metal. This weight M, in the normal position of the bottle, seats] in a shallow recess Z provided in the upper surface of the casing L. The casing, L is slidable in the member A and it is provided with arched recesses R round its lower edge. It may be provided with slight ridges 1' at its upper and lower edges respectively;

The cover portion of the member A is provided 5 with an inclined interior upper surface S and a recess P, the diameter of which is only slightly greater than that of the reduced portion m of the weight M so that the recess acts as a guide for the weight when it is displaced due to the movement of the bottle. A pin m prevents excessive lateral displacement.

The sleeve G is formed at its lower end with a cylindrical boss 0, and a corkor rubber ring N is held between this boss and the base of the member A. The external diameter of the ring N is slightly greater than that of the member A to provide a tight joint between the stopper and the neck of the bottle.

Threads Q are provided on the neck of the bottle for the reception of a screw cap. Any other form of cap may of course be used.

In assembling the component members of the stopper the ring N is placed in position on the sleeve G. The disc J, float K, casing L and weight M are then placed in position and this assembly is telescoped carefully into the hollow cylindrical member A till the pins F pass into the bayonet recesses E. Then by compressing the ring N and twisting the pins can be snapped over the arch of the bayonet recesses thereby forming one unit.

The stopper may then be inserted into the neck of a bottle and it is driven down till the upper surface is preferably just belowthe upper surface of the neck of the bottle. This assists in protecting the stopper from withdrawal.

When the bottle is inverted for pouring the upper part of the weight M drops into the recess P and then and then only the pressure between the disc J and the flange H is released and the force of the liquid in the bottle lifts the disc right off itsseat and-thereby the recesses R and ports D come into complete register. Liquid then passes through these ports and flows out between the lugs C and through the grooves B. Until the extension m has entered the recess P the weight holds the parts sealed whether the bottle ,be upright or not, since the top of the extension 1n will engage the face S.

If liquid is attempted to be introduced into the bottle while it is in an inverted position the disc J is pressed against the seating H by the buoyancy of the float K in liquid which passes through the ports D and R and liquid is thus prevented from passing from the stopper into the bottle.

When the bottle is in an horizontal or upright position the weight M presses the disc J against the seating H thus preventing liquid from passing into the bottle.

It is to be understood that the invention is not to be restricted to the details shown and described by way of example; for instance the component parts of the stopper may be formed of any materials which are suitable for the purpose, the details in construction of the parts may be varied and other modifications may be made within the scope of the accompanying claims.
